4-1-4 Interference with Proximity Sensors

V600-H07 R/W Head
When facing the same direction, V600-H07 R/W Heads should be installed at
least 550 mm apart (center to center) if RD/WT commands are used, and1,200
mm apart (center to center) if auto commands are used.
When facing each other, V600-H07 R/W Heads should be installed at least 200
mm apart regardless of whether RD/WT commands or auto commands are
used.
When facing the same direction, V600-H07 R/W Heads should be installed at
least 200 mm apart regardless of whether RD/WT commands or auto com-
mands are used.
Note For applications in which no two R/W Heads transmit or receive data at the same
time (i.e., in which the R/W Heads read and write independently), there is no risk
of mutual interference and the R/W Heads can be installed in proximity. Trans-
mission and reception in this case refer to the R/W Heads oscillating after receiv-
ing commands.
V600-series R/W Heads use electromagnetic linking (frequency: 530 kHz), so, if
they are installed near sensors (such as proximity sensors) with an oscillation
frequency of 400 to 600 kHz, it may cause the sensors to malfunction. Before
installing R/W Heads, and when selecting sensors, be sure to conduct tests to
make sure that there will be no interference.
As shown in the following diagrams, a V600-H07 R/W Head should be at least
400 mm from a proximity sensor when the two are facing the same direction or
550 mm min.
(1,200 mm min.)
200 mm min.
